# 按键绑定 #

在编辑不同的语言时，使用的语法解析不同，需要根据语法进行过滤后加入按键绑定。  
如下, context中当view.scope\_name() == ‘source.diff’时，才能激活使用按键绑定:

{
            // Navigate to results with enter key
            "keys": ["enter"],
            "command": "diff_visiter",
            "context": [{
       "operand": "source.diff", 
                    "operator": "equal", 
                    "match_all": true, 
                    "key": "selector"
                    }]
                }

# diff跳转代码 #

当在diff语法的view中，直接按回车能够跳转到对应代码实现。

class DiffVisiterCommand(sublime_plugin.TextCommand):
        def __init__(self, *args, **kwargs):
            print("DiffVisiter init")
            super(DiffVisiterCommand, self).__init__(*args, **kwargs)
    
        def run(self, edit):
            print("call diffvisitor")
            if self.view.settings().get('syntax') == DIFF_SYNTAX_FILE:
                print("diff visitor")
                filepath = self.view.substr(self.view.line(0))
                linenum_re = re.compile(r'^([0-9])*[ac]([0-9]+)')
    
                for region in self.view.sel():
                    # Find anything looking like file in whole line at cursor
                    if not region.empty():
                        break
    
                    match_line = self.view.substr(self.view.line(region))
                    print('match line: %s' % match_line)
                    re_match_linenum = linenum_re.search(match_line)
    
                    # if this line had a line number, use it and look up for the filename
                    if re_match_linenum:
                        lineno = re_match_linenum.group(2)
                        line_beg = self.view.line(region).begin()
                        prev_line_bounds = self.view.line(sublime.Region(line_beg - 1, line_beg - 1))
                        file_line = self.view.substr(prev_line_bounds)
                    else:
                        lineno = '1'
    
                    print("Opening file '%s'" % (filepath + ":" + lineno))
                    sublime.active_window().open_file(filepath + ":" + lineno, sublime.ENCODED_POSITION)
